PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, the web_crawl() function in praisonaiagents/tools/web_crawl_tools.py accepts arbitrary URLs from AI agents with zero validation. No scheme allowlisting, hostname/IP blocklisting, or private network checks are applied before fetching. This allows an attacker (or prompt injection in crawled content) to force the agent to fetch cloud metadata endpoints, internal services, or local files via file:// URLs. This vulnerability is fixed in 1.5.128.

Affected: PyPI: praisonaiagents

## Summary

The `web_crawl()` function in `praisonaiagents/tools/web_crawl_tools.py` accepts arbitrary URLs from AI agents with zero validation. No scheme allowlisting, hostname/IP blocklisting, or private network checks are applied before fetching. This allows an attacker (or prompt injection in crawled content) to force the agent to fetch cloud metadata endpoints, internal services, or local files via `file://` URLs.

## Details

The `web_crawl()` function at `web_crawl_tools.py:182` accepts a URL string or list of URLs and passes them directly to HTTP clients without any SSRF protections:

```python # web_crawl_tools.py:182-234 def web_crawl( urls: Union[str, List[str]], provider: Optional[str] = None, ) -> Union[Dict[str, Any], List[Dict[str, Any]]]: # Normalize to list single_url = isinstance(urls, str) # ... url_list = [urls] if single_url else urls # No URL validation whatsoever — urls flow directly to providers if selected == "tavily": results = _crawl_with_tavily(url_list) elif selected == "crawl4ai": results = _crawl_with_crawl4ai(url_list) else: results = _crawl_with_httpx(url_list) # Always-available fallback ```

The `_crawl_with_httpx()` fallback at line 133 makes the actual requests:

```python # web_crawl_tools.py:140-150 try: import httpx with httpx.Client(follow_redirects=True, timeout=30.0) as client: response = client.get(url) # Line 143: fetches ANY URL, follows r…
